Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I posted this before and got a lot of help. Sadly, I can't find my original post. So here is the question again.
If I read in an environment variable such as:
$user = $ENV {'Mike', 'Wallace'};
How can I remove the white space and get just the last name Wallace.
Thank you in advance.

Okay, I'm about to break the habit of a lifetime and answer this. I think your initial post on this matter was here. If it isn't your post it's still the same basic question so your answer should be there.

Now I've been useful a couple of hints. If you're going to be asking questions it's worth registering a username so you can easily go back and view your own posts, and also it's definitely worth noting down useful tips in a notebook or something (Yes, a paper one. No CPU needed).

Now for a quick check.. I think you've managed to mangle your question somewhere, or do you really have an enviroment variable called (not 'with the value of', but called) 'Mike Wallace'?

actually, the poster specified (my code tags for clarity) $user = $ENV {'Mike', 'Wallace'};, which is not a valid way to recover a single key from %ENV.

either he's looking for an array of environment vars (not likely), in which case he'd specify @ENV, or he's looking for a key named Mike', 'Wallace (which is valid on Win32,) which is referenced by $ENV{'Mike\', \'Wallace'}. NOTE: this is platform specific--i can't find a way to set an environment variable with quotes on solaris or cygwin.

s/\s*//g; will remove all the whice space in your var, as to your specfic one, you could do something like (split /\,/,$user)[1] Which would return the word after the second comma and before the third (if there is one). And have you tried super search?
